South Korea’s parliament on Thursday passed a law that abolishes Korea’s two traditional methods of counting ages. It was announced that from June 2023, the so-called “Korean Age” system will no longer be allowed in official documents. Deciding to use the standardized, internationally accepted method instead, South Korea cites the reason for this change as “to clear up confusion”.
South Korea will become one to two years younger

Therefore, there is a significant confusion in Korea, which has three different age counting systems. For example, on December 9, 2022, a person born on December 31, 2002 is 19 years old in the international system, 20 in the counting system, and 21 in the Korean system.
Yoo Sang-bum of the ruling People’s Power Party told parliament that “the revision aims to reduce unnecessary socio-economic costs because confusion remains due to legal and social disagreements, as well as different ways of calculating age.” These calculation differences also negatively affect the provision of medical and administrative services.
